Description

Technical FieldThe present invention relates to an electric wire inserting jig for inserting electric wires into a corrugated pipe and an electric wire automatic inserting device for inserting electric wires into a corrugated pipe using such an electric wire inserting jig.BackgroundConventionally, an electric wire insertion jig is used for inserting electric wires into a corrugated tube (see, for example, Patent Document 1). The electric wire insertion jig of Patent Document 1 is a bottomed tubular member whose front end is tapered and closed into a wedge shape, and is configured such that the insertion ends of the electric wires are inserted into the corrugated tube from an opening on the rear end side. In order to insert the electric wires into the corrugated tube, the electric wires are inserted into the corrugated tube together with the electric wire insertion aid into which the insertion ends have been inserted. Then, the electric wire inserting jig moves into the corrugated tube before the electric wires to guide the insertion of the electric wires.Prior ArtPatent DocumentPatent Document 1: JP2010-104082ASUMMARY OF THE INVENTIONProblem SettingIn the above-mentioned electric wire insertion jig of Patent Document 1, the end of the electric wire insertion jig is frequently thickened so that the wedge-shaped end does not hang and deform as it moves in the corrugated tube. If the end is thicker, the electric wire insertion aid is larger. And, when the difference between the inner diameter of the corrugated tube and the outer diameter of the electric wire is small, it may be difficult to use the electric wire inserting jig.In view of the above problems, it is an object of the present invention to provide an electric wire insertion jig that can be effectively used even when the difference between the inner diameter of the corrugated tube and the outer diameter of the electric wire is small, and an automatic electric wire insertion apparatus using such an electric wire insertion jig.Solution to ProblemsIn order to solve the above-mentioned problems, an electric wire insertion jig includes: an electric wire insertion part formed in a cylindrical shape and into which an end part of an electric wire is inserted; A guide part connected to the electric wire insertion part on a side opposite to an electric wire insertion hole in an axial direction of the electric wire insertion part, wherein at least a distal end of the guide part in the axial direction is formed with a curved surface in a curved convex shape from an outer periphery to an axial center, wherein when the guide part is inserted and moved in a corrugated tube, the curved surface rubs against an inner surface of the corrugated tube, so that the guide part assists a movement, in the corrugated tube, of the electric wire insertion part following the guide part and into which the end part has been inserted, to thereby guide the insertion of the electric wire into the corrugated tube.In order to solve the above problems, an electric wire automatic insertion device includes: the above electric wire insertion jig; a pipe holding part that holds the corrugated pipe in an elongated state; and an electric wire guide part that holds the electric wire such that the electric wire can be guided from an electric wire guide-out opening spaced apart from a first end opening of the corrugated pipe held by the pipe holding part and guides the electric wire such that the electric wire passes through the inside of the corrugated pipe from the first end opening to a second end opening; a jig conveying part that includes a gripping mechanism for gripping the electric wire insertion jig and can convey the electric wire insertion jig gripped by the gripping mechanism; and an insertion control unit, causing the auxiliary tool conveying part to convey the electric wire insertion auxiliary tool to a position between the first end opening of the corrugated tube and the electric wire lead-out opening and causing the electric wire lead-out part to lead-out the electric wire until an end part of the electric wire is inserted into the electric wire insertion part, wherein the insertion control unit causes the gripping mechanism of the auxiliary tool conveying part to release the electric wire insertion auxiliary tool and causes the electric wire lead-out part to lead-out the electric wire until the electric wire insertion auxiliary tool protrudes from the second end opening so that the electric wire is inserted into the corrugated tube, and thereafter, the plug-in control unit causes the jig conveying part to grip the electric wire plug-in jig protruding from the second end opening to release the electric wire plug-in jig from the end part.Advantageous Effects of the InventionThe electric wire insertion jig and the electric wire automatic insertion device having the above-mentioned configuration can be effectively used even when the difference between the inner diameter of the corrugated tube and the outer diameter of the electric wire is small.Brief Description of the DrawingsFIG. 1 is a perspective view showing an electric wire automatic insertion device according to an embodiment.

FIG. 2 is an enlarged perspective view showing the electric wire insertion jig shown in FIG. 1. FIG. 3 is a view showing end portions of electric wires inserted into the electric wire inserting jig of FIG. 2, the electric wire inserting jig being partially shown in section to show the inside thereof.The electric wire automatic insertion device 1 according to the present embodiment is a device that automatically inserts two electric wires W 1 into the inside of a corrugated tube C 1 having a cylindrical bellows shape. The electric wire automatic insertion device 1 includes an electric wire insertion jig 10, a pipe holding part 20, an electric wire take-out part 30, a jig conveying part 40, a jig stopper 50, a device frame 60, and an insertion control unit 70.The electric wire insertion jig 10 is a substantially cylindrical jig that is attached to end parts W 11 of the electric wires W 1 and used to insert the electric wires W 1 into the corrugated tube C 1. As shown in FIGS. 2 and 3, the electric wire insertion tool 10 includes an electric wire insertion part 11, a guide part 12, a connection / gripping part 13, and an insertion securing part 14.The electric wire insertion part 11 has a cylindrical shape and is a part into which the end parts W 11 of the two electric wires W 1 are inserted.The guide part 12 is a part connected via a connection / grip part 13 to a side of the electric wire insertion part 11 opposite to an electric wire insertion hole 111 in an axial direction D 11 along the axis X 1 of the electric wire insertion part 11. The guide part 12 includes a cylindrical part 121 and a distal curved surface part 122. The cylindrical part 121 is coaxial with and has the same diameter as the electric wire insertion part 11 having the cylindrical shape. The distal curved surface part 122 is provided at the end of the cylindrical part 121 on the side opposite to the electric wire insertion part 11 so as to extend to the distal end of the guide part 12. The outer surface of the distal curved surface part 122, which is the distal end side of the guide part 12 in the axial direction D 11, has a curved surface 122 bhaving a curved convex shape from the outer periphery 122 ato the axial center X 1. In this embodiment, the curved surface 122 bis a hemispherical surface. When the guide part 12 is inserted and moved in the corrugated tube C1, the curved surface 122b of the distal curved part 122 rubs against the inner surface of the corrugated tube C1. By such a movement, the guide part 12 assists the movement of the electric wire insertion part 11 following the guide part 12 and into which the end parts W 11 of the electric wires W 1 have been inserted, in the corrugated tube C 1, and guides the insertion of the electric wires W 1 through the corrugated tube C 1. In addition, the guide part 12 is provided with a guide hole 123 for guiding the insertion securing part 14, which extends cylindrically along the axial center X 1 and opens at the center of the curved surface 122 bof the distal curved surface part 122.The connecting / gripping part 13 connects the electric wire insertion part 11 and the guide part 12 to each other, and is formed in a narrower narrowed shape than the electric wire insertion part 11 and the guide part 12. The narrowed shape of the connection / gripping part 13 is shaped such that the connection / gripping part 13 can be gripped by a gripping mechanism 41 of the auxiliary conveying part 40 of the electric wire automatic insertion device 1 of FIG. 1.The electric wire insertion part 11, the guide part 12, and the connection / grip part 13 described above are integrally formed of metal.The insertion securing part 14 of the electric wire insertion jig 10 is a member for securing insertion of the end parts W 11 of the electric wires W 1 into the electric wire insertion part 11, and includes a rod-shaped part 141, an electric wire contact part 142, and a bias coil part 143. The rod-shaped part 141 is a round rod-shaped part that can be moved in the axial direction D 11 through the inside from the electric wire insertion part 11 to the guide part 12 and is accommodated along the axial center X 1 while being spring-biased in the biasing direction D 12 toward the electric wire insertion hole 111. In the guide part 12, the rod-shaped part 141 passes through the inside of the guide hole 123, so that the front end of the rod-shaped part 141 can protrude from a guide hole 123 aat the center of the curved surface 122 bof the far curved surface part 122. The electric wire contact part 142 is a cylindrical part integrally formed at the rear end of the rod-shaped part 141 and is shorter and larger in diameter than the rod-shaped part 141. The electric wire contact part 142 is disposed inside the electric wire insertion part 11, and when the end parts W 11 of the electric wires W 1 are inserted into the electric wire insertion part 11, the end parts W 11 come into abutment with the electric wire contact part 142. The rod-shaped part 141 and the electric wire contact part 142 are integrally formed of metal. The biasing spring part 143 is a spring part disposed around the rod-shaped part 141 in a compressed state between the electric wire contact part 142 and the inner wall surface in the electric wire securing part 11 on the guide part 12 side. Due to the arrangement in a compressed state, the bias coil part 143 spring-biases the rod-shaped part 141 and the electric wire contact part 142 in the bias direction D 12 as mentioned above.When the end parts W 11 of the electric wires W 1 are inserted into the electric wire insertion part 11, the end parts W 11 come into abutment with the electric wire contact part 142 to press the electric wire contact part 142 in the direction reverse to the biasing direction D 12. Then, in the insertion securing part 14, the rod-shaped part 141 is pressed by the electric wires W 1 and moves against the biasing force, so that a front end part 141 aof the rod-shaped part 141 protrudes from the guide hole 123 aof the guide hole 123 through the curved surface 122 bof the distal curved surface part 122. In the insertion securing part 14, the front end part 141 aprotruding from the curved surface 122 bis used to ensure insertion of the end parts W 11 of the electric wires W 1 into the electric wire insertion part 11. FIG. 2 shows the state in which the front end part 141 aof the rod-shaped part 141 is retracted before the electric wires are inserted into the guide hole 123 aby the spring biasing, while FIG. 3 shows the state in which the front end part 141 aprotrudes from the guide hole 123 aafter the electric wires are inserted against the spring biasing.The electric wire insertion aid 10 has been described above. Next, other components of the electric wire automatic insertion device 1 of FIG. 1 will be explained.The pipe holding part 20 of the electric wire automatic insertion device 1 is a part that holds the corrugated pipe C 1 in an elongated state and has a pair of holding parts 21 that hold both ends of the corrugated pipe C 1. The corrugated pipe C1 is conveyed to the pipe holding part 20 by a predetermined pipe feeding device. The pipe holding part 20 receives and holds, by means of the pair of holding parts 21, both ends of the corrugated pipe C 1 conveyed by the pipe feeding device. In this case, the electric wire insertion jig 10 and the corrugated tube C 1 are arranged such that the axial direction D 11 of the electric wire insertion jig 10 and the longitudinal direction D 13 of the corrugated tube C 1 coincide with each other.The electric wire lead-out part 30 is a mechanism that holds the electric wires W 1 such that the electric wires W 1 can be lead out from an electric wire lead-out port 31 disposed at a position spaced apart from a first end opening C 11 of the corrugated tube C 1 held by the tube holding part 20. The electric wire leading-out part 30 leads out the electric wires W 1 from the electric wire lead-out opening 31 such that the electric wires W 1 pass through the inside of the corrugated tube C 1 from the first end opening C 11 to a second end opening C 12. In this case, the lead-out direction D 14 of the electric wires W 1 provided by the electric wire lead-out part 30 is a direction from the first end opening C 11 to the second end opening C 12 along the longitudinal direction D 13 of the corrugated tube C 1.The tool conveying part 40 is a mechanism that includes the gripping mechanism 41 for gripping the electric wire insertion tool 10 and can convey the electric wire insertion tool 10 gripped by the gripping mechanism 41. The auxiliary machine conveying part 40 includes not only the gripping mechanism 41 but also a vertical movement mechanism 42, a front-rear movement mechanism 43, a lateral movement mechanism 44, and a front-rear fine adjustment mechanism 45.The gripping mechanism 41 of the jig conveying part 40 is a mechanism for gripping the electric wire insertion jig 10, and is a mechanism part for gripping the electric wire insertion jig 10 in a gripping direction D 161 along a jig thickness direction D 16 crossing a vertical direction D 15 along the gravity and the axial direction D 11. The gripping mechanism 41 includes a pair of gripping arms 411 that can move in the gripping direction D 161 and an opposite releasing direction D 162, and grips the electric wire insertion jig 10 by clamping the constricted connection / gripping part 13 of the electric wire insertion jig 10 with the pair of gripping arms 411. The vertical movement mechanism 42 is a mechanism part that holds the gripping mechanism 41 by the front-rear fine adjustment mechanism 45 and can move the gripping mechanism 41 in the vertical direction D 15. The front-rear moving mechanism 43 is a mechanism part that holds the vertical moving mechanism 42 by the lateral moving mechanism 44. The front-rear moving mechanism 43 can move the gripping mechanism 41 in a front-rear direction D 17 along the longitudinal direction D 13 of the corrugated pipe C 1 held by the pipe holding part 20 by the vertical moving mechanism 42. The traverse mechanism 44 is a mechanism part that is held by the front-rear movement mechanism 43 and holds the vertical movement mechanism 42. The traverse mechanism 44 may move the gripping mechanism 41 via the vertical movement mechanism 42 in a traverse direction D 18 crossing the vertical direction D 15 and the front-rear direction D 17. The front-rear fine adjustment mechanism 45 is a mechanism part that is held by the vertical movement mechanism 41 and holds the grip mechanism 41, and can finely adjust the position of the grip mechanism 41 in the front-rear direction D 17.The jig stopper 50 is a mechanism part that receives the electric wire insertion jig 10 protruding from the second end opening C 12 at a receiving position P 11 on the outside of the second end opening C 12 of the corrugated pipe C 1.FIG. 4 is an enlarged perspective view showing the jig stopper shown in FIG. 1 receiving the electric wire insertion jig protruding from a second end opening of the corrugated tube.As shown in FIG. 4, the jig stopper 50 includes a jig receiving part 51 and a receiving cylinder mechanism 52. the jig receiving part 51 is a U-shaped member that is positioned at the receiving position P 11 and receives, by means of a U-shaped inner part, the electric wire insertion jig 10 protruding from the second end opening C 12 of the corrugated pipe C 1 when the insertion of the electric wires W 1 is completed. The receiving cylinder mechanism 52 is a mechanism part that moves the auxiliary material receiving part 51 between a predetermined retreat position P 12 and the receiving position P 11 in a stopper moving direction D 19 along the auxiliary material thickness direction D 16 in which the gripping mechanism 41 of the auxiliary material conveying part 40 grips the electric wire insertion auxiliary material 10. The electric wire insertion jig 10 received by the jig receiving part 51 of the jig stopper 50 is gripped by the gripping mechanism 41 of the jig conveying part 40, and then the receiving cylinder mechanism 52 retracts the jig receiving part 51 to the retracting position P 12. This retraction of the jig receiving part 51 provides a space on the opposite side of the gripping mechanism 41 gripping the electric wire insertion jig 10 from the second end opening C 12 of the corrugated pipe C 1. When the gripping mechanism 41 moves from this space in the front-rear direction D 17, the electric wire insertion jig 10 is removed from the end parts W 11 of the electric wires W 1 of which insertion has been completed.The apparatus frame 60 is a metal frame approximately in the form of a table, and various mechanism parts including the pipe holding part 20, the electric wire lead-out part 30, the auxiliary conveying part 40, and the auxiliary stopper 50 are mounted at positions corresponding to the table surface.The plug-in control unit 70 is mounted at a position in the device frame 60 where it does not interfere with the movements of the various mechanism parts, and is a control part that performs computer control of the automatic operation of the electric wire automatic plug-in device 1. Specifically, the insertion control unit 70 controls operations of the pipe holding part 20 that receives and holds the corrugated pipe C 1 from the pipe feeding device, the electric wire executing part 30 that executes the electric wires W 1, the auxiliary conveying part 40 that conveys the electric wire insertion auxiliary 10, and the auxiliary stopper 50.FIG. 5 is a view explaining how the electric wire insertion jig is transported by the jig conveying part before the electric wires are led out through the electric wire lead-out part, and how the electric wires are inserted into the electric wire insertion jig through the electric wire lead-out part.In the step shown in FIG. 5, the workpiece conveying part 40 conveys, under the control of the insertion control unit 70, the electric wire insertion jig 10 to a position between the first end opening C 11 of the corrugated tube C 1 held by the tube holding part 20 and the electric wire lead-out opening 31 of the electric wire lead-out part 30. In detail, the jig conveying part 40 conveys the electric wire insertion jig 10 gripped by the gripping mechanism 41 to an insertion start position P 13 on the electric wire lead-out opening 31 side between the first end opening C 11 and the electric wire lead-out opening 31, until the end parts W 11 of the electric wires W 1 are inserted into the electric wire insertion part 11. Here, the gripping mechanism 41 is provided with an auxiliary tool insertion detecting unit 412 that detects that the end parts W 11 of the electric wires W 1 are inserted into the electric wire insertion part 11. As described above, when the electric wires are inserted, the front end part 141 aof the insertion securing part 14 protrudes from the curved surface 122 bof the curved convex shape of the guide part 12. The jig insertion detection unit 412 is a sensor that photoelectrically detects the protrusion of the front end part 141 a. That is, the tool insertion detection unit 412 projects the detection light L 1 to a position where protrusion of the front end part 141 ais expected. When the front end part 141 adoes not protrude, the detection light easily passes through this position. When the front end part 141 aprotrudes, the detection light L 1 is reflected and reflected by the front end part 141 a. The auxiliary tool insertion detection unit 412 detects protrusion of the front end part 141 a, i.e., insertion of the end parts W 11 of the electric wires W 1 into the electric wire insertion part 11, when the detection light L 1 reflected in this manner is received. The insertion control unit 70 causes the electric wire execution part 30 to execute the electric wires W 1 until the auxiliary insertion detection unit 412 detects the insertion of the electric wires, and causes the electric wire execution part 30 to stop the execution when the insertion of the electric wires is detected.When the insertion of the electric wires into the electric wire insertion jig 10 is completed in this manner by the insertion of the end parts W 11 of the electric wires W 1 into the electric wire insertion part 11, the electric wires W 1 and the electric wire insertion jig 10 are inserted into the corrugated tube C 1.FIG. 6 is a view showing the first step of inserting electric wires into the corrugated tube, which is performed after the electric wires are inserted into the electric wire inserting jig. FIG. 7 is a view showing the second step of inserting the electric wires into the corrugated tube, which follows the first step of FIG. 6. In FIG. 7, the corrugated tube C1 is partially shown in section to show how the electric wires W1 are inserted into the corrugated tube C1 together with the electric wire inserting aid 10.First, in the first step of FIG. 6, the guide part 12 of the electric wire insertion jig 10 gripped by the gripping mechanism 41 exposed to the first end opening C 11 is inserted into the first end opening C 11 of the corrugated pipe C 1 as shown in FIG. 5. This first-step insertion operation is performed under the control of the insertion control unit 70 such that the front-rear fine adjustment mechanism 45 of the tool conveying part 40 moves the electric wire insertion tool 10 into which the electric wires have been inserted (i.e., the gripping mechanism 41) in the front-rear direction D 17 toward the first end opening C 11. This movement is continued until the pair of grip arms 411 of the grip mechanism 41 comes into abutment with the holding part 21 of the pipe holding part 20 holding one end of the corrugated pipe C1. As a result, the grip part 12 exposed from the pair of grip arms 411 is inserted into the first end opening C 11 of the corrugated pipe C 1. At the same time, the electric wire guide part 30 guides the electric wires W 1 of a size corresponding to the movement of the gripping mechanism 41.In the second step of FIG. 7 following the first step, first, under the control of the insertion control unit 70, the pair of grip arms 411 of the grip mechanism 41 of the jig conveying part 40 is opened to release the gripping of the electric wire insertion jig 10. After releasing, the vertical movement mechanism 42 moves the gripping mechanism 41 upward in the vertical direction D 15, and the transverse movement mechanism 44 moves the gripping mechanism 41 laterally in the transverse direction D 18. Further, the front-rear moving mechanism 43 moves the gripping mechanism 41 in the front-rear direction D 17 to the second end opening C 12 of the corrugated pipe C 1 in preparation for removing the electric wire insertion jig 10 with which the insertion has been completed. In parallel with this operation of the jig conveying part 40, the insertion control unit 70 inserts the electric wires W 1 into the corrugated tube C 1 by causing the electric wire executing part 30 to execute the electric wires W 1 until the electric wire insertion jig 10 protrudes from the second end opening C 12. At this time, the electric wire executing part 30 continues executing the electric wires W 1 until the execution amount preset in correspondence with the corrugated tube C 1 is reached. The execution amount is set to a value sufficient for the electric wire insertion jig 10 to protrude from the second end opening C 12. When the electric wires W 1 are inserted in this manner, the second end opening C 12 of the corrugated tube C 1, which is the outlet for the electric wires W 1, is placed in a standby state in preparation for the electric wires W 1 to reach the second end opening C 12, as explained later.FIG. 8 is a view showing the standby state in preparation for the arrival of the electric wires produced on an opposite second side while the electric wires are inserted into the corrugated tube.In the standby state of FIG. 8, the gripping mechanism 41 of the auxiliary conveying unit 40 moves the second end opening C 12 of the corrugated pipe C 1 in parallel with the insertion of the electric wires W 1 under the control of the insertion control unit 70, and is positioned in front of the second end opening C 12. At this time, the pair of grip arms 411 of the grip mechanism 41 is in an open state. Further, the auxiliary agent receiving part 51 of the auxiliary agent stopper 50 is positioned at the retreat position P 12 in the stopper moving direction D 19. When the insertion of the electric wires W 1 proceeds and the electric wire insertion jig 10 attached to the end parts W 11 of the electric wires W 1 protrudes from the second end opening C 12, the state of the jig stopper 50 changes as follows in response to the protrusion of the electric wire insertion jig 10 under the control of the insertion control unit 70.FIG. 9 is a view showing a change of the auxiliary agent stopper from the standby state shown in FIG. 8 in response to the electric wire insertion auxiliary agent at the end parts of electric wires protruding from the second end opening of the corrugated tube. FIG. 10 is an enlarged perspective view of the auxiliary agent receiving part of the auxiliary agent stopper shown in FIG. 9 as viewed from the direction of the arrow V 11 in FIG. 9.At this stage, the jig receiving part 51 of the jig stopper 50 is moved in the receiving direction D 191 from the retreat position P 12 shown in FIG. 8 to the receiving position P 11 in response to the electric wire insertion jig 10 protruding from the second end opening C 12 of the corrugated pipe C 1. When the electric wire insertion jig 10 finally sufficiently protrudes from the second end opening C 12, the guide part 12 of the electric wire insertion jig 10 is received in the U-shaped inner part of the jig receiving part 51 and fitted at the receiving position P 11. At this stage, the pair of grip arms 411 of the grip mechanism 41 remains in an open state. When sufficient insertion of the electric wires W 1 into the corrugated tube C 1 and reception of the electric wire insertion jig 10 are completed, the state of the second end opening C 12 proceeds to the next step under the control of the insertion control unit 70.FIG. 11 shows how the state at the second end opening side of the corrugated tube shifts to the next step after the electric wire insertion jig shown in FIGS. 9 and 10 is received.When receiving the electric wire insertion jig 10 is completed, first, under the control of the insertion control unit 70, the pair of grip arms 411 of the grip mechanism 41 are closed in the grip direction D 161 to grip the electric wire insertion jig 10. When the insertion of the electric wires is completed, the electric wire insertion jig 10 is gripped by the gripping mechanism 41 at the insertion completion position P 14 in the vicinity of the second end opening C 12 of the corrugated tube C 1, and then removed from the end parts W 11 of the electric wires W 1 as described later. At this time, the tool receiving part 51 of the tool stopper 50 is moved in the retreat direction D 192 from the receiving position P 11 to the retreat position P 12 shown in FIGS. 9 and 10. Further, the tool insertion detection unit 412 of the gripping mechanism 41 detects that the end parts W 11 of the electric wires W 1 are inserted into the electric wire insertion part 11 of the electric wire insertion tool 10 in the protruding state. This detection is performed by the tool insertion detection unit 412 that photoelectrically detects that the front end part 141 aof the insertion securing part 14 protrudes from the curved surface 122 bin the curved convex shape of the guide part 12, similarly to the detection during the initial insertion of the electric wires into the electric wire insertion tool 10 of FIG. 5.FIG. 12 shows how the jig insertion detection unit detects that the end parts of the electric wires are inserted into the electric wire insertion part of the electric wire insertion jig in a state protruding from the second end opening of the corrugated tube. FIG. 13 shows a state in which a problem occurs with the insertion of the end parts of the electric wires into the electric wire insertion jig in the protruding state, and the jig insertion detection unit cannot detect that the end parts of the electric wires are inserted into the electric wire insertion part.When the insertion of the end parts W 11 of the electric wires W 1 into the electric wire insertion jig 10 is detected in the protruding state, the jig insertion detection unit 412 also projects a detection light L 1 to a position where protrusion of the front end part 141 ais expected. As shown in FIG. 12, when the end parts W 11 of the electric wires W 1 are sufficiently inserted and the front end part 141 aprotrudes to the expected position, the detection light L 1 is reflected and reflected by the front end part 141 a. The auxiliary tool insertion detection unit 142 detects protrusion of the front end part 141 a, i.e., insertion of the end parts W 11 of the electric wires W 1 into the electric wire insertion part 11 by receiving the detection light L 1 reflected in this manner. On the other hand, as shown in FIG. 13, when the end parts W 11 of the electric wires W 1 are not sufficiently inserted and the front end part 141 adoes not protrude, the detection light L 1 passes through this position, and the auxiliary insertion detection unit 412 does not detect the detection light L 1. In this case, when the tool insertion detection unit 412 does not detect the insertion of the end parts W 11 of the electric wires W 1, the insertion control unit 70 determines that a malfunction has occurred and the electric wire insertion tool 10 has been separated or just separated during the insertion of the electric wires. Then, the plug-in control unit 70 stops the operation of the electric wire automatic plug-in device 1 and notifies the operator of an alarm.When the jig insertion detection unit 412 successfully detects insertion of the electric wires into the electric wire insertion jig 10 in the above state, the insertion control unit 70 determines that the insertion of the electric wires W 1 into the corrugated pipe C 1 has been successfully completed. In this case, under the control of the plug-in control unit 70, the following prepared operations are performed in preparation for the plug-in of electric wires into a new corrugated pipe.FIG. 14 shows preparatory operations performed after completion of the insertion of the electric wires into the corrugated tube to insert further electric wires into a new corrugated tube.When it is determined that the insertion of the electric wires W 1 into the corrugated tube C 1 has been successfully completed, the insertion control unit 70 operates the jig conveying part 40 for removing the electric wire insertion jig 10 protruding from the second end opening C 12 and gripped by the gripping mechanism 41 from the end parts W 11 of the electric wire W 1. At this time, the front-rear fine adjustment mechanism 45 moves the gripping mechanism 41 in a direction away from the second end opening C 12 to thereby pull the electric wire insertion jig 10 out of the end parts W 11 of the electric wires W 1. Thereafter, the traverse mechanism 44 and the vertical movement mechanism 42 are operated to retract the electric wire insertion jig 10 laterally in the traverse direction D 18 and upward in the vertical direction D 15. Further, the front-rear moving mechanism 43 moves the electric wire insertion jig 10 of which interference with the corrugated pipe C 1 has been prevented by the above-mentioned retraction in the front-rear direction D 17 to the electric wire take-out part 30. furthermore, the vertical moving mechanism 42, the traverse moving mechanism 44, and the front-rear fine adjustment mechanism 45 are operated to move the electric wire insertion jig 10 to the insertion start position P 13 shown in FIG. 5. At the insertion start position P 13, the electric wire insertion jig 10 is used for inserting the electric wires W 1 into a new corrugated tube.The electric wire insertion jig 10 and the electric wire automatic insertion device 1 according to the above-described embodiment can achieve the following advantages. In the electric wire insertion jig 10 according to this embodiment, the distal end side of the guide part 12 that precedes the electric wire insertion part 11 during insertion of the electric wires W 1 into the corrugated tube C 1 is formed with a curved surface 122 bin the curved convex shape from the outer periphery 122 ato the axial center X 1. The curved surface 122 bin the curved convex shape prevents the end of the guide part 12 from being caught or deformed when moving inside the corrugated pipe C 1. As a result, an increase in the thickness of the guide part 12 and an associated increase in the electric wire insertion aid 10 can be mitigated. Thus, even if the difference between the inner diameter of the corrugated tube C 1 and the outer diameter of the electric wires W 1 is small, the electric wire insertion jig 10 can be formed with a corresponding size, and the electric wire insertion jig 10 can be effectively used during the insertion of the electric wires W 1 into the corrugated tube C 1.In this embodiment, in the guide part 12 of the electric wire insertion jig 10, the curved surface 122 bon the distal end side is a hemispherical surface. According to this configuration, the possibility that the end of the guide part 12 formed on the hemispherical curved surface 122 bremain caught inside the corrugated tube C 1 is further reduced. Due to this further sticking preventing effect, the electric wire insertion aid 10 can be used more effectively when the electric wires W 1 are inserted into the corrugated tube C 1.Further, in this embodiment, the electric wire insertion jig 10 is provided with the connection / gripping part 13 having the narrowed shape that can be gripped by the gripping mechanism 41. According to this configuration, the connection / gripping part 13 allows the electric wire insertion jig 10 to be gripped effectively by the gripping mechanism 41. The electric wire automatic insertion device 1 provided with the gripping mechanism 41 can effectively automate the insertion of the electric wires W 1 into the corrugated tube C 1 using the electric wire insertion jig 10.Further, in this embodiment, the electric wire insertion jig 10 is provided with the insertion securing part 14 which extends inward from the electric wire insertion part 11 toward the guide part 12 and moves against the spring bias by being pushed by the electric wires W 1 so that the front end part 141 aprotrudes from the curved surface 122 b. In this insertion securing part 14, the front end part 141 aprotruding from the curved surface 122 bis used to ensure insertion into the electric wire insertion part 11. According to this configuration, by ensuring the protrusion of the front end part 141 aon the insertion securing part 14 from the curved surface 122 bof the guide part 12, it can be effectively ensured that the end parts W 11 of the electric wires W 1 are sufficiently inserted into the electric wire insertion part 11.Further, in the electric wire automatic insertion device 11 of the present invention, since the electric wire insertion jig 10 explained above is used, the electric wire insertion jig 10 can be effectively used even if the difference between the inner diameter of the corrugated tube C 1 and the outer diameter of the electric wires W 1 is small. Further, with the automatic electric wire inserting apparatus 1 of this embodiment, by operating the electric wire lead-out part 30 and the auxiliary conveying part 40 under the control of the insertion control unit 70, the electric wires W 1 can be inserted into the corrugated pipe C 1 continuously and without manual intervention during the operations.Further, in this embodiment, the electric wire automatic insertion device 1 is provided with the tool insertion detection unit 412 that detects that the end parts W 11 of the electric wires W 1 are inserted into the electric wire insertion part 11 of the electric wire insertion tool 10. When the tool insertion detection unit 412 detects that the end parts W 11 are inserted into the electric wire insertion tool 10 disposed between the first end opening C 11 of the corrugated pipe C 1 and the electric wire lead-out opening 31, the insertion control unit 70 starts to lead out the electric wires W 1 into the corrugated pipe C 1. With this configuration, after the jig insertion detection unit 412 detects the insertion, the electric wires W 1 are executed so that the electric wires W 1 can be inserted into the corrugated tube C 1, effectively preventing separation of the electric wire jig 10.Further, in this embodiment, in the electric wire automatic insertion device 1, the insertion control unit 70 releases the insertion jig 10 when it is detected that the end parts W 11 of the electric wires W 1 are inserted into the electric wire insertion jig 10 protruding from the second end opening C 12 of the corrugated tube C 1 after completion of the insertion. With this configuration, when the electric wire insertion jig 10 is removed, the jig insertion detection unit 412 performs insertion detection. Detection at this time enables effective detection of situations in which, during the insertion, the electric wire insertion jig 10 was moved inside the corrugated tube C 1 separately or with insufficient insertion of the electric wires and the end parts W 11 of the electric wires W 1 could not reach the second end opening C 12.Further, in this embodiment, the electric wire insertion device 1 is provided with an auxiliary agent stopper 50. The jig stopper 50 is a part that receives the electric wire insertion jig 10 protruding from the second end opening C 12 at the receiving position P 11 on the outside of the second end opening C 12 of the corrugated pipe C 1. The auxiliary agent stopper 50 moves the auxiliary agent receiving part 51 between the predetermined retreat position P 12 and the receiving position P 11 in the stopper moving direction D 19 along the auxiliary agent thickness direction D 16. The insertion control unit 70 moves the tool receiving part 51 to the receiving position P 11 in response to the electric wire insertion tool 10 protruding from the second end opening C 12 and causes the tool conveying part 40 to grasp the electric wire insertion tool 10 received by the moved tool receiving part 51. Thereafter, the insertion control unit 70 retracts the tool receiving part 51 to the retreat position P 12. With this configuration, when the insertion is completed, the electric wire insertion jig 10 protruding from the second end opening C 12 of the corrugated pipe C 1 is received at the fixed receiving position P 11 by the jig receiving part 51 of the jig stopper 50. By this receiving, the electric wire insertion aid 10 can be smoothly transferred to the automatic electric wire insertion apparatus 1 for subsequent operations.Further, in this embodiment, in the electric wire automatic insertion device 1, the gripping mechanism 41 of the jig conveying part 40 serves as a mechanism for gripping the electric wire insertion jig 10 in the jig thickness direction D 16. This configuration is preferable because the gripping mechanism 41 grips the electric wire insertion jig 10 in the jig thickness direction D 16, causing less interference with the corrugated tube C 1 and the electric wires W 1 or other mechanism parts on the device in the gripping state, as compared to gripping in the vertical direction D 15 or the axial direction D 11.Further, in this embodiment, in the electric wire automatic insertion device 1, the auxiliary conveying part 40 includes the vertical movement mechanism 42 that holds the gripping mechanism 41 and the front-rear movement mechanism 43 that holds the vertical movement mechanism 42. According to this configuration, the electric wire insertion jig 10 gripped by the gripping mechanism 41 can be moved by the vertical movement mechanism 42 and the front-rear movement mechanism 43 while effectively avoiding interference with the corrugated pipe C 1 and various mechanism parts on the apparatus.Further, in this embodiment, in the electric wire automatic insertion device 1, the auxiliary conveying part 40 includes the traverse mechanism 44 held by the front-rear movement mechanism 43 and holding the vertical movement mechanism 42. According to this configuration, the degree of freedom of movement of the gripping mechanism 41 by the jig conveying part 40 and thus the degree of freedom of movement of the electric wire insertion jig 10 is greater, so that the electric wire insertion jig 10 can be moved while more effectively avoiding interference with the corrugated pipe C 1 and various mechanism parts.Further, in this embodiment, in the electric wire automatic insertion device 1, the auxiliary conveying part 40 includes the front-rear fine adjustment mechanism 45 held by the vertical movement mechanism 42 and holding the gripping mechanism 41. This configuration enables fine adjustment of the front-rear direction D 17 in the final stage of positioning the electric wire insertion jig 10 to the insertion start position P 13 or the insertion completion position P 14, so that the accuracy of positioning to these target positions can be improved.The above-described embodiment shows only typical shapes of the electric wire insertion jig and the electric wire automatic insertion device. The electric wire insertion jig and the electric wire automatic insertion device are not limited thereto, and may be implemented with various modifications.For example, in the above description, the electric wire insertion jig 10 having the substantially cylindrical shape for inserting the electric wires W 1 into the corrugated pipe C 1 having a cylindrical bellows shape and the electric wire automatic insertion device 1 having the electric wire insertion jig 10 described above are described as an example of the electric wire insertion jig and the electric wire automatic insertion device. However, the electric wire insertion jig and the electric wire automatic insertion device are not limited thereto. The corrugated tube into which the electric wires are inserted is not limited to a cylindrical shape, and may be, for example, an elliptical bellows tube. Further, the electric wire insertion jig is not limited to a cylindrical shape, and may be, for example, a member having an elliptic cylindrical shape as long as the shape can be moved in the corrugated tube. Thus, as for the electric wire insertion jig and the electric wire automatic insertion device, the specific cylindrical shape of the corrugated tube into which the electric wires are inserted and the specific cylindrical shape of the corresponding electric wire insertion jig may be any shape.Further, in the above-described embodiment, the electric wire insertion jig 10 and the electric wire automatic insertion device 1 for inserting two electric wires W 1 into the inside of the corrugated pipe C 1 will be described as an example of the electric wire insertion jig and the electric wire automatic insertion device. However, the electric wire insertion jig and the electric wire automatic insertion device are not limited thereto, and the specific number of electric wires to be inserted into the corrugated tube may be any number, and accordingly, the specific number of electric wires to be inserted into the electric wire insertion jig may be any number.Further, in the above-described embodiment, the guide part 12 whose distal end side curved surface 122 bis a hemispherical surface will be described as an example of the guide part of the electric wire insertion jig. However, the shape of the curved surface of the guide part is not limited to a hemispherical shape, and no specific specification is made here for the shape of the curved surface. As described above, the guide part 12 having a hemispherically curved surface 122 ballows the electric wire insertion jig 10 to be used more effectively in inserting the electric wires W 1 into the corrugated tube C 1.Further, in the above-described embodiment, the electric wire insertion jig 10 having the connection / gripping part 12 having the narrowed shape will be described as an example of the electric wire insertion jig. However, the electric wire insertion jig is not limited thereto. The electric wire insertion part and the guide part may be formed integrally and continuously without the narrowed shape being provided therebetween. However, as described above, the connection / gripping part 13 enables the narrowed shape to effectively automate the insertion of the electric wires W 1 by causing the gripping part 41 to grip the electric wire insertion jig 10.Further, in the above-described embodiment, the electric wire insertion jig 10 including the insertion securing part 14 on which the front end part 141 aprotrudes from the curved surface 122 bon the distal end side will be described as an example of the electric wire insertion jig.

However, the electric wire automatic insertion device is not limited thereto, and the electric wire automatic insertion device may also start executing the electric wires without performing electric wire insertion auxiliary agent insertion detection at the start of the insertion. However, as described above, when the insertion of the electric wires W 1 is detected and then the execution of the electric wires W 1 is started, separation of the electric wire insertion jig 10 can be effectively prevented when the electric wires W 1 are inserted into the corrugated tube C 1.Further, in the above-described embodiment, the electric wire automatic insertion device 1 of which the electric wire insertion jig 10 is removed after the jig insertion detection unit 412 detects the insertion of the electric wires W 1 into the electric wire insertion jig 10 after the completion of the insertion is described as an example of the electric wire automatic insertion device. However, the electric wire automatic insertion device is not limited thereto, and after completion of the insertion, the electric wire insertion jig can be removed from the electric wires without performing insertion detection into the electric wire insertion jig. However, as described above, when the insertion of the electric wires W 1 is detected and then the electric wire insertion jig 10 is removed, separation or insufficient insertion of the electric wires during the insertion can be effectively detected.Further, in the above-described embodiment, the electric wire automatic insertion device 1 including the auxiliary agent stopper 50 that receives the electric wire insertion auxiliary agent 10 protruding from the second end opening C 12 of the corrugated pipe C 1 at the receiving position P 11 will be described as an example of the electric wire automatic insertion device. However, the electric wire automatic insertion device is not limited thereto, and the electric wire automatic insertion device may proceed to following operations without particularly receiving the electric wire insertion jig at the second opening side of the corrugated pipe. However, as described above, when the electric wire insertion jig 10 is received at the second end opening C 12 of the corrugated pipe C 1, the electric wire insertion jig 10 can be smoothly transferred to the following operations.Further, in the above-described embodiment, the gripping mechanism 41 that grips the electric wire insertion jig 10 in the jig thickness direction D 16 crossing the vertical direction D 17 and the axial direction D 11 will be described as an example of the gripping mechanism of the jig conveying part. However, the gripping mechanism is not limited thereto, and the gripping mechanism can grip the electric wire insertion jig also in the vertical direction or the axial direction. However, the gripping mechanism 41 that grips the electric wire insertion jig 10 in the jig thickness direction D 16 and causes a smaller interference during gripping is preferable.Further, in the above-described embodiment, the auxiliary conveying part 40 including the vertical movement mechanism 42 and the front-rear movement mechanism 43 will be described as an example of the auxiliary conveying part. However, the auxiliary conveying part is not limited thereto, and the auxiliary conveying part may be, for example, a robot arm or the like whose moving direction is not specified. However, the tool conveying part 40 including the vertical movement mechanism 42 and the front-rear movement mechanism 43 can convey the electric wire insertion tool 10 more inexpensively than a robot arm that is more complex in structure and more expensive. Further, with the above-described configuration, the electric wire insertion jig 10 can be moved while effectively avoiding interference with the device.Further, in the above-described embodiment, the auxiliary conveying part 40 further including the lateral movement mechanism 44 in addition to the vertical movement mechanism 42 and the front-rear movement mechanism 43 will be described as an example of the auxiliary conveying part. However, the auxiliary material conveying part is not limited thereto, and the auxiliary material conveying part may be a function provided only by the vertical moving mechanism and the front-rear moving mechanism. However, the above-described transverse movement mechanism 44 enables movement of the electric wire insertion jig 10 with more effective prevention of interference.Further, in the above-described embodiment, the auxiliary conveying part 40 further including the front-rear fine adjustment mechanism 45 in addition to the vertical movement mechanism 42 and the front-rear movement mechanism 43 will be described as an example of the auxiliary conveying part. However, the auxiliary material conveying part is not limited thereto, and the auxiliary material conveying part may have a function constituted only by the vertical moving mechanism and the front-rear moving mechanism. However, the front-rear fine adjustment mechanism 45 can improve the accuracy in positioning the electric wire insertion jig 10 to a desired position.List of Reference Numerals1 Electric wire automatic insertion device 10 Electric wire insertion jig 11 Electric wire insertion part 12 Guide part 13 Connection / gripping part 14 Insertion securing part 20 Pipe holding part 21 Holding part 30 Electric wire guide part 31 Electric wire lead-out opening 40 Jig conveying part 41 Gripping mechanism 42 Vertical movement mechanism 43 Front-rear movement mechanism 44 Traverse movement mechanism 45 Front-rear fine adjustment mechanism 50 Jig stopper 51 Jig receiving part 52 Receiving cylinder mechanism 60 Device frame 70 Insertion control unit 111 Electric wire insertion opening 121 Cylindrical part 122 Further curved surface part 122 a Außenumfang periphery 122 b Curved surface 123 Guide hole 123 a Guide opening 141 Rod-shaped part 141 a Front end part 142 Electric wire contact part 143 Bias coil part W 11 End Part X 1 Axial CenterReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
